GUI programming in Elixir?

If you have web development experience, I would recommend Electron. It’s fairly easy to build and distribute a desktop application if you already have experience with web technologies. I wrote an app using Elm and distributed it as an Electron app.

elixir and a server and elm as a frontend is pretty popular right now. I’ve actually started working on something built that way (though I’m not sure if I’m going to use electron, or just the browser).
